Hi JJHaggar.

Thank you very much for your help. I will post it in the repository issues and hope for an answer.

Thanks again and best regards

hello everyone, do any of you know (or are any of you bored enough to write) a script which would dither the image based on:

currently active palette
custom dither pattern (ideally in format aseprite uses for dither with gradient tool)?

why: while it is not hard to create dithering manually with gradient tool and custom brushes, editing image already full of dithering can be pretty painful and time consuming. with dithering script user could simply use opacity and add dithering only in last step before export.

Two new scripts added to the first post

Aseprite Mega Drive Digitizer (by themrcul)
Center the current selection on the sprite (by tuxpup)

@Olga_Galvanova That seems a really difficult task I fear ^^U If somebody makes a script for Aseprite I’d be delighted, but meanwhile you can use Photoshop or Pixatool for that

hey, thanks for the tips! another great method for dithering pictures with custom patterns is dan fessler’s index painting - if you make your gradient map to match your palette and posterizing steps. that method works even in after effects.

however, i just found out that the script isn’t actually necessary
you can select installed dither patterns when converting to indexed (sprite -> color mode -> more options)
omg
patterns seem to be duplicated (ordered dithering + name, old dithering + name (for some reason this seems to get better results)) but they work.
i can’t believe i didn’t notice it sooner.

Hi, I wrote a little extension that reduces the bit-depth of the palette. This can be useful when designing sprites for retro-hardware.

github.com

sandord/aseprite-scripts/blob/master/Reduce palette bit-depth.lua

local spr = app.activeSprite

if not spr then
  return app.alert("There is no active sprite")
end

local dlg = Dialog("Reduce palette bit-depth")

local function showHelp()
  app.alert{title="Help", text={
    "This extension reduces the bit-depth of each palette color, which could be desirable if you",
    "want to match the color limitations of retro hardware such as an Atari ST.",

Made a script for importing existing tags from the exported JSON. Useful so you don’t have to re-tag every animation for similar sprites:

github.com

jestarray/aseprite-scripts/blob/master/jest_import_existing_tags.lua

local json = { _version = "0.1.1" }

-------------------------------------------------------------------------------
-- Encode
-------------------------------------------------------------------------------

local encode

local escape_char_map = {
  [ "\\" ] = "\\\\",
  [ "\"" ] = "\\\"",
  [ "\b" ] = "\\b",
  [ "\f" ] = "\\f",
  [ "\n" ] = "\\n",
  [ "\r" ] = "\\r",
  [ "\t" ] = "\\t",
}

local escape_char_map_inv = { [ "\\/" ] = "/" }
for k, v in pairs(escape_char_map) do

Is this malware free?

JJHaggar · August 18, 2020, 5:28am

Hi @sandor and @jest! Thanks a lot for sharing your scripts! I have just added them to the first post!

Yes, this malware is 100% free.

Sorry XD Jokes aside, the scripts are plain text and most of them are on github ( commonly used to host open-source projects), so you can literally read what the scripts do

AseAseAse · August 18, 2020, 5:37am

hello guys…I am really having trouble selecting the right colors, especially for 32 bit, choosing the right color is a big deal. So how about adding an option or tool which would make color picking that much easier?

For example, I will pick 2 colors (black, white) then the system/tool will suggest the best “in-between” color(gray) to make the in between color harmonize or mix well with the other 2 colors.

JJHaggar · August 18, 2020, 6:31am

@AseAseAse If I have understand you correctly, there is already a script for that, “Hue Generator”

I don’t want to be harsh or anything, but you should probably search in the script list before requesting new script functionalities ^_^U

devilsgarage · August 18, 2020, 6:55am

wow, love this script! Thank you for making and sharing!

AseAseAse · August 18, 2020, 8:51am

it does not work Annotation 2020-08-18 164935

JJHaggar · August 18, 2020, 9:51am

@AseAseAse I have just tried that script and it works perfectly. Are you using the last version of Aseprite? Have you downloaded the correct file?

When downloading scripts from github repositories you must right click on “raw” button and then choose “save as” to get the correct file, if not you could be saving an “html” file instead of the “lua” file that you need.

I hope it helps!

AseAseAse · August 18, 2020, 10:16am

I will try, I’m new in aseprite, thanks!

JJHaggar · August 18, 2020, 10:28am

No problem! And welcome to Aseprite community! ^_^/

Gasparoken · October 14, 2020, 4:33pm

I made a tool for animate an image (multi-layer allowed) according a desired path, gif mini tutorial included, enjoy!
PathAnimator
Tank3FLATTEN
Github repository: here
This tank was done with ‘path_animator.lua’ (caterpillar pads, tank vibration, tree shadow) and ‘rotar.lua’ (the wheels):
The most very basic tutorial of this tool:
T01-TranslationLineal-RotationNone
You can report issues on gasparoken@gmail.com

Olga_Galvanova · October 14, 2020, 4:58pm

oh, wow, this is very impressive! thanks for sharing.

KashouC · December 8, 2020, 7:32pm

Oh wow this is great. Good work.

Merge All Tabs

github.com

jestarray/aseprite-scripts/blob/master/jest_merge_all_tabs.lua

--[[ 
    This script merges every opened tab into 1 sprite. 
    Useful becase aseprite only groups 1 level, so if you have images like:
      Monster_walk_east_0
      Monster_walk_east_1

      Monster_attack_east_0
      Monster_attack_east_1
    
    it will create 2 tabs when really you want these combined together into 1 sprite because they're animations relating to an entire unit
    
    script by jest(https://github.com/jestarray) - for aseprite versions > 1.2.10
    
    Public domain, do whatever you want
 ]]

if #app.sprites < 1 then
  return app.alert "You should have at least one sprite opened"
end

It will just combine all your open tabs into 1 spritesheet.
Someone please tell me if there’s a built in way to do this…

Tenome · January 2, 2021, 5:21am

In the throes of my beginner stages, I assembled various animations from an existing spritesheet into layers on top of each other. Is there a way to export each layer as its own GIF? The Export option lets you select a layer to export, but is there a script that will automate the rest (similar to the Export All Layers as PNG script)?

Pic related, I would want Idle.gif, Stand 1.gif, Stand 2.gif, etc. without the layers overlapping (so it would have to reveal and hide the layers one by one during the procedure). I searched and couldn’t find a script that did this. Thanks for any help.
